Looking at increase test failure rates I found that the Machine Configuration Operator is impacted by the following problem:

master: 'pool is degraded because nodes fail with "1 nodes are reporting degraded status on sync": "Node master-1.ostest.test.metalkube.org is reporting: \"unexpected on-disk state validating against rendered-master-b53a676afd716529294c720496e1c1d8: content mismatch for file \\\"/etc/NetworkManager/dispatcher.d/30-resolv-prepender\\\"\""' worker: all 3 nodes are at latest configuration rendered-worker-f44d30c0b5f48fd0e2ebb6c3bf92f09b

Here's a link to the job run I saw: https://prow.ci.openshift.org/view/gs/test-platform-results/logs/periodic-ci-openshift-release-master-nightly-4.16-upgrade-from-stable-4.15-e2e-metal-ipi-upgrade-ovn-ipv6/1767453873359818752

Component Readiness has found a potential regression in [sig-arch][Early] CRDs for openshift.io should have subresource.status [Suite:openshift/conformance/parallel].

Probability of significant regression: 97.35%
